[anickone]

This is done as follows.

def reader(filename):
    with open(filename) as fin:
        txt = fin.read()
    lines=txt.strip().split('\n')
    outerdict={}
    for line in lines:
        lst=line.split()
        outerdict[lst[1]]={
            'number' : int(lst[0]),
            'grade'  : int(lst[2]),
            'total'  : int(lst[3]),
            'weight' : float(lst[4]),
        }
    return outerdict
